GRAIN TESTER.

Application led May 18, 1925.

The invention relates to improvements in grain testers and an object ofthe invention is to provide a tool whereby a person, such as a grainmerchant, can quickly and effectively test a sample of grain.

A further object of the invention is to previde a. simply constructed,inexpensive, durable and easily operated tool and one which can bereadily adapted for testing various kinds of grains.

With the above more important objects in view the invention consistsessentially in the arrangement and construction of parts hereinaftermore particularly described and later pointed out in the appended claim,reference being had to the accompanying drawing in which:

Fig. 1 is a perspective view of the tester with the knife in Openposition.

Fig. 2 is a vertical sectional view longitudinally and centrally throughthe tester and with the knife open.

Fig. 3 is a plan view of one end of the tester with the knife open andthe pressure 25 disc removed.

Fig. 4 is an inverted plan view of the parts appearing in Fig. 3.

In the drawing like characters of reference indicate corresponding partsin the several `figures.

The tester comprises four main parts; a cup 1, a knife 2, a holder 3 anda pressure disc 4. The cup, knife and holder are all supplied withhandles 5, 6 and 7 respectively, the handles being pivotally connectedtogether by a fastening bolt 8 fitted with a nut 9.

It is to be observed that the knife operates between the cup and theholder and that the knife handle can swing in between the other handles,a space 10 being reserved for this purpose between the handles 5 and 7.The ends of the handles 5 and 7 are fitted with opposing complementarystop plugs 11 and 12 which stop the said handles from turning in onedirection after they have been brought to the position shown best inFigure 1.

The knife 2 might be called a circular or Serial No. 31,225.

shearing knife and it is arranged to cutv across the face of the holder3.

The cup 1 is provided with a perforated bottom as indicated at 13 andthe yholder 3 is supplied with perforations 14 forming pockets opposingthe perforations 13 when the tester is closed. The perfo-rations andpockets are forme'dwith due regard t0 the particular grain which is tobe tested.

At the side opposite pin 8 the cup 1 is provided with a retaining finger1 shaped to t beneath and support the adjacent edge of the holder 3 whenthe'latter is in closed position as shown to advantagepin Figure 2.

In the present instance a sample of wheat 15 is being tested and theperforat-ions 13 are of such a nature that they will allow the wheatkernels to press through in an end on position and the pockets 14 aresuch that they will receive and support the lower ends of the saidkernels, it being understood that Ehe knife is at this time in the openposi` ion.

When one wishes to test a sample of wheat he puts the sample in the cupand then shakes the cup to cause a quantity of the kernels to take anendon position with their lower ends seated in the pockets, the knife bladebeing at this time open. He then inserts the pressure member o-r disc 4and whilst pressing down on it he draws the handle 6 inwardly betweenthe handles 5y and 7, such resulting in the cutting in two by the knifeblade of the kernels caught in the pockets. After cutting he swings theknife blade and cup to the side and this exposes the horizontally cutkernels held in the pockets. One can then examine these for toughness,frost or vermin as is customarily done.

In connection with the tester I might remark that I will make sets ofcups and, holders having the perforations and pockets designed forvarious kinds of grains so that with a set of these one could test thevario-us grains as desired.

What I claim as my invention is: y

In a grain tester, a cup for receiving the sample t0 be tested having aperforated bottoni and provided with un extending handle, a holdernormally located beneath the cup and having pockets therein opposing theperlorations, said holder being provided with an extending handle, ncutting knife interposed between the Cup and the holder, seid' cuttingknife being provided with an extending handle, a pin pivotnllyconnecting the handles together, :i Weighted disc loosely insertedWithin the cup und u re- 10 taining linger carried by the cup at theSide reinote iti-oni the pin and receiving the :xdjncentedge of theclosed holder.
